The Suffolk County Water Authority experienced a historic surge in water main breaks during the recent winter season, as extreme cold placed unprecedented strain on the region’s aging infrastructure.
From December through February, SCWA crews responded to 504 main breaks, marking the highest number recorded during that three-month period in at least ten years.
The spike in incidents closely tracked with plunging temperatures, particularly during February 2026, which alone accounted for 245 breaks. January also proved demanding, with 121 repairs completed, including a single week in which crews addressed 44 separate breaks. Officials attributed the increase to deep freezes that drove frost lines further into the ground than usual, causing soil movement and placing significant pressure on older cast iron pipes.
Despite harsh and often dangerous conditions, SCWA crews worked continuously to maintain water service for approximately 1.2 million residents across Suffolk County. Workers frequently operated in sub-zero temperatures, navigating icy terrain while performing urgent repairs.
“The work our crews performed was truly heroic,” said SCWA Chairman Charlie Lefkowitz, emphasizing the physical demands and commitment required to sustain operations during the severe weather.
In response to ongoing challenges, the authority continued its infrastructure renewal efforts, replacing roughly 20 miles of aging water main with more durable ductile iron pipe. The upgraded material is designed to better withstand temperature fluctuations and reduce the likelihood of fractures. Replacement efforts focused on areas with recurring break patterns, aiming to strengthen the system’s long-term reliability.
SCWA Chief Executive Officer Jeff Szabo praised employees for their dedication, noting that their efforts ensured uninterrupted service during a particularly difficult winter. He also highlighted expanded hours at the Customer Contact Center, which helped address increased service inquiries during peak cold periods.
The Suffolk County Water Authority operates as a public-benefit corporation, providing water service on a not-for-profit basis without taxing authority, and continues to invest in improvements to meet the needs of the communities it serves.
